Amazon calculates a product’s star ratings using a machine learned model instead of a raw data average. The machine learned model takes into account factors including: the age of a review, helpfulness votes by customers and whether the reviews are from verified purchases.
When it comes to skincare, I', a brand hunter. Olay is a great brand and at Amazon's prices, you can't go wrong. I'm 51 and this cream keeps the moisture in my skin all night and into the morning. Highly recommend
